Specification of Letters Patent.

Application filed August 2, 1912. Serial No. 712,888.

To all whom it may concern:

Be it known that I, Acorn L. HANsEN, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented a certainnew and useful Improvement in Safety Oil-Cans, of which the following is a specification. I

My invention relates to that class of cans which are designed to hold explosive liquids, and has for its object to provide a can, which will permit the expansion of the fluid in the can, due to a change of temperature, to raise the valve from its seat and thus relieve the excess pressure without danger of an explosion, and has for its further object to provide a can which will not leak if accidentally overturned or even deliberately turned upside down, and has for its further ob]ect to provide a vertical inlet with securing means to hold the funnel in positionduring the operation of filling, and has for its further object to provide an air vent operated by the same lever which 0 crates the valve, th.us insuring a smooth an easy flow of the liquid.

My means of accomplishing the foregoing may be more geadily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which: The drawing illustrates a side view of my improved safety can,

purpose of clearness.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawing, 1 is the can proper, which has secured to its upper wall a casing 2, which contains the valve mechamsm and the spout 3 for the egress of the liquid and the inletopening 4. This casin is secured to the top of the can by means 0 rivets 5 or by any other suitable means. The casing 2 has a downwardly projecting flange 6, WhlCh extends down within the interior of the can and which is provided with a plurallty of openings similar to the openmg 7, and is'provided with a auze 8 to prevent any ossible passage of ame to the in terior oft ecan.

9 is the valve proper, which is provided wlth a metal seat 10, which is preferably formed of lead or some other soft metal, maintain a tight oint betweenltself and the valve seat 11 very cheap and satisfacto the upper part being broken away and shown in section for the 29 enters.

cured in position by means ofa screw 18,

the stem passing through a slot 20 formed in a manually operated lever 19.

21 is the valve for the air vent, which is provided with a stem 22, the latter being surrounded by a coil spring 23, which opcrates to hold the valve 21 to its seat. The said s ring 23, bears against the washer moun (1 upon the valve seat 22, which bears against the lever 19. As the strength of the spring 15 is greater than that of the spring 23, it follows that the, latter is unable to move the lever 19 outwardly. This makes a construction.

The outer end 24 of t e valve stem 22 passes through a slot 25 formed in the lever 19. This lever is pivotally attached by means of a pin or pivot 26 to outwardly extending lugs 27 cast or formed on the chamher 2. 28 is a cap for closing the inlet opening 4.

The operation of the device is as follows: The manually operated lever 19 is drawn outwardly carrying with. it the valve 9-.

This carries with it an upwardly extending rod 29, which is secured to the valve 9, a recess 80 bein provided into which the rod. T e funnel is then inserted, as shown in the dotted lines, and the pressure of the sprin serves to' press the rod 29 against the fmnel and hold it rigidly in position for filling the can:

- It will be apparent to persons skilled in.

the art from the fore oing statement, that thus it is easily possib e to fill the can with- 'out .the slightest danger of the explosive fluid being spilled. -At the same time upon removal of the funnel and the release by the operator of the manually operated lever 19,

the coil springs 15 and 23 serve to instantly seat the valves 9 and 21, securely closing these openings, so that there is no possibility of the liquid escaping when the can is over-- turned! At. the same time it will be noted t at the valves open outwardly, therefore any excess of pressure caused by change of temperature will merely operate to lift the valves and relieve the excessive pressure.

' Having described my invention, what I regard as new and desire to secure by Letters Patent is:

1. A safety can having a casing secured thereto, a spout leading from said casingya cylindrical sleeve formed in said casing, a valve seat at its lower end, an outwardly opening valve slidable in said cylinder fit- ,ting to the valve seat, a plug closing said cylindrical sleeve, a coil spring surrounding in said cylinder fitting to the valye seat, a

the valve stem, which holds said valve to its seat, a manually operated lever pivotally attached to said casing wall, there being a slot formed therein through which the valve stem passes, an outwardly opening air vent valve seated in a cylindrical passage, the stem of which passes through a slot in the lever, a coil spring which holds the vent closed under normal conditions and means to attach both valve stems to the lever.

2. A safety can having a casing secured thereto, a spout leading from said casing, a cylindrical'sleeve formed in said casing, a valve seat at its lower end, a valve slidable lever, a coil spring which holds the vent closed under normal conditions and means to attach both valve stems to the lever, whereby they can move freely outwardly without moving the lever.

3. A safety can having a casing secured thereto, a spoutleading from said casing, a cylindrical sleeve formed in said casing, a valve seat at its lower end, an outwardly opening valve slidable in saidcylinder fitting tothe'valve seat, a plug closing said cylindrical sleeve, a coil spring surrounding the valve stein, which holds said valve to its seat, a manually;, operated lever pivotally attached to said casing wall, there being a slot formed therein through which the valve stem passes, an air ventvalve, seated in a cylindrical passage, the stem of which passes through a slot. in the lever, a coil spring which holds the vent closedv under normal conditions, means to attach bothvalve stems to the lever, a flange having a plurality of openings in its wall depending downwardly from said casing and a cap of wire gauzesecured to said flange.

4. A safety can havin a casing secured thereto, a spout leading om said casing, a

cylindrical sleeve formed in said casing, a valve seat at its lower end, a valve slidable in said cylinder fitting to the valve seat, a plug closing said cylindrical sleeve, a coil spring surrounding the valve stem which holds said valve to its seat, a manually operated lever pivotally attachedto said casing wall there being a slot formed therein through which the valve stem passes, an

outwardly opening air vent valve, seated in a cylindrical passage, the stem of which passes through a slot in the lever, a coil' spring which holds the vent closed under normal conditions, means to attach both valve stems to the lever, a flange having a plurality of openings in its walldepending downwardly from said casing, a cap of wire gauze secured to said flange, both the air vent and the main valve passage leading from said gauze protected chamber.

5. A safety can having a casing secured thereto, a spout leading from said casing, a
